I covered various features of Java 8 as given below.

1. For the given below main concepts

-Lambda expressions

-Method references

-Functional interfaces

-Stream API

-Parallel Stream

-Default methods

-Static methods in the interface

-Optional class

-Collectors class

-ForEach() method

-Predicate

-Supplier

-Consumer

-BiFunction

examples you have to go through of all the concepts also to implement at least 1 program for each concept.

2. Implement a Java program with Stream API and without the Stream API, consider filter conditions as for example you had an employee list filter the employee records whose salary >1000 $, Name Starts with B & D and age > 30.

It must be written in Java Language.
